88 Mr. Adam White's Description 



from analogy and examination of many specimens, I believe to 

 be the female of the other. Dr. Burmeister, on the authority of a 

 letter, quotes t\\e Scutellera coralUfera oi ^ldic\ea.y as synonymous 

 with the ruhro-maculata. In the Appendix to King's Voyage, 

 vol. ii. p. 466, this species is described ; and if not the same as 

 the Scutellera dux, Kirby (Linn. Trans, xii. p. 474), and Sc. 

 basalts, G. R. Gray, (Griff. A. K. Ins. ii. p. 233, pi. 92), it is a 

 very closely allied species. Had Dr. Burmeister ever seen Mr. 

 Macleay's , description, he would not have been led into this mis- 

 application of the synonyme. 



CoLEOTicHus, White, in Mag. Nat. Hist. u. s. p. 541. 



Tetyra costata of Fabricius seems to me to have characters 

 entitling it to the rank of a genus, which might be placed between 

 Tetyra as restricted by Burmeister {Eurygaster, Laporte) and 

 Pachychoris, to a species of which it has a considerable degree of 

 resemblance. If no name has been previously assigned it, I 

 would suggest that of Coleotichus. Its characters are as follows : 



Head somewhat square, in front triangular, eyes prominent. 

 Beak four-jointed, reaching to base of hind pair of legs, joints 

 nearly of equal length, the second the most slender, received in a 

 sternal groove, the walls of which project between first pair of 

 legs, behind which they gradually diminish in height, increasing 

 in thickness as they approach the second pair, beyond this they are 

 very broad, and in front surround the trochanter of hind pair of 

 legs. (PI. VII. fig. 2.) Antennae rather short (situated on underside 

 of head about midway between eye and beak, the base concealed 

 from view by the projecting flap of underside of prothorax), five- 

 jointed, first, third and fifth nearly equal in length, second shortest, 

 and fourth rather the longest, all the joints cylindrical. Thorax 

 nearly as long as broad, much rounded posteriorly. Scutellum 

 as long as abdomen (which it entirely covers), with a slightly 

 raised dorsal line. Body above depressed, beneath considerably 

 flattened. 



Coleotichus costatus was first described from a specimen in the 

 Banksian Cabinet, and is still preserved there. Donovan figured 

 this specimen, but his figure is bad. This species does not seem 

 to be common in collections, and is apparently unknown on the 

 continent.* The British Museum collection contains two muti- 

 lated individuals from New Holland. 



* I have just seen Germar's Monograph of the Scutelleridce , published ia his 

 "Zeitschrift fvir die Entomologie ;" he arranges this insect in the genus Tetyra, 

 as restricted by some authors, but he has evidently not seen the species, as his
